Is there anyway to permanently treat ptsd?

Sometimes.: Exposure therapy and emdr are very effective in reducing or eliminating ptsd symptoms. Whether symptoms are eliminated or only reduced depends on how severe, complex, prolonged, human caused, and early in life the trauma was. Torture, prolonged combat or abuse, and trauma that occurs early in life are often the most difficult. Substance abuse and additional disorders complicate recovery.

Sometimes: Ptsd may resolve permanently for some people. However for many it remains an albatross. For the most severe cases of complex ptsd a goal is controlling one's symptoms rather than the symptoms controlling their life.

Management: Typically with the more severe cases of PTSD, the medical/psychological is not so much about curing it, as it is about effectively managing it. It never goes away in the sense of being cured. In a way both patients and doctors are students of managing severe cases of PTSD, and never master of controlling it, unfortunately.
